So many of my settings were reset to the worst possible selections. It took 3 weeks to get my email back to almost functional. I went from two days for a charge to less than two hours. Email no longer auto deleted the oldest. It reloaded from the oldest to the newest and never reached the newest. It loaded most emails twice. Available memory was reduced. Contact list "lost" many, many contacts. Had to go through ALL setup options from scratch. Fortunately had help from former Apple employee who knew the setup. Even he became very frustrated. This last set of iOS updates seemed like intentional sabotage. Very disappointed in Apple.
